Study of compact antenna for UWB applications

Abstract-This paper comes with a new low cost compact planar antenna with the improvement of the bandwidth. This structure is based on an FR4 substrate. To develop this structure we have conducted many optimizations by using Momentum integrated into ADS "Advanced Design System" from Agilent Technologies and compared with CST Microwave studio. The comparison between simulation and measurement results permits to validate the final achieved antenna structure with an improvement of the bandwidth. The antenna achieved is a low cost planar, simple in structure and easy to be fabricated, thus promising for applications in wireless communication systems.Index Terms-Bandwidth improvement, microstrip antennas, wide band antennas.

“…Unfortunately, achieving a compact geometry and maintaining acceptable electrical performance are conflicting goals and, in practice, a compromise solution has to be sought. In the case of UWB antennas, reduction of size (and, consequently, a ground plane) leads to shortening the current path and matching problems at lower frequencies [2]. A number of techniques have been developed to alleviate this difficulty, such as various ground plane modifications (e.g., I-shaped [6] and L-shaped stubs [7], protruded ground plane structures [8], slits below the feed line [7], stripline-fed designs [9], etc.)…”

In this paper, a novel structure of a compact UWB slot antenna and its design optimization procedure has been presented. In order to achieve a sufficient number of degrees of freedom necessary to obtain a considerable size reduction rate, the slot is parameterized using spline curves. All antenna dimensions are simultaneously adjusted using numerical optimization procedures. The fundamental bottleneck here is a high cost of the electromagnetic (EM) simulation model of the structure that includes (for reliability) an SMA connector. Another problem is a large number of geometry parameters (nineteen). For the sake of computational efficiency, the optimization process is therefore performed using variable-fidelity EM simulations and surrogate-assisted algorithms. The optimization process is oriented towards explicit reduction of the antenna size and leads to a compact footprint of 199 mm 2 as well as acceptable matching within the entire UWB band. The simulation results are validated using physical measurements of the fabricated antenna prototype.
